The radius of a circle is 3 miles. What is the circle's area?
Use 3.14 for βπ.
The area of the circle is 28.26 square miles.
To find the area of a circle, we use the formula:
Area = π Γ radiusΒ²
Substituting the given value, we get:
Area = 3.14 Γ 3Β²
Area = 3.14 Γ 9
Area = 28.26
Therefore, the area of the circle is 28.26 square miles.
To find the area of a circle, you can use the formula: A = π * r^2, where A is the area and r is the radius.
Given that the radius of the circle is 3 miles, we can substitute it into the formula:
A = 3.14 * 3^2
Simplifying the exponent:
A = 3.14 * 9
Calculating:
A = 28.26
Therefore, the area of the circle is 28.26 square miles.
